I noticed one had a swollen foot, I had a feeling when I saw it what it was but I've never dealt with or seen it before. I took her to my chicken vet when I looked at it and noticed it was also on the other foot and dripping pus. Since she is the one who is always picked on already he was concerned about re-introducing her after her treatment. So he found her a loving forever home with an experienced chicken owner who was willing and kind enough to take her on. I cannot be exposed to staph right now, my immune system is low due to radiation, if I get it, it won't be good. Meanwhile he told me to check the other hens, they all had it. Not nearly as bad but both feet on all of them. He feels they will recover with antibiotics for 14 days. I checked their roost and the rest of the coop/run for the cause. Nothing. The only thing we can come up with is it has been blazing hot and they burned thier feet on the deck and or pavement. Anyone have this happen?
